The optical fiber turn serial converter is a kind of multifunctional RS - 232 / RS422 / RS485 interface optical fiber MODEM. Is to connect remote terminal unit (RTU) to HOST (HOST) or distributed data collection system (SCADA) controller is the best choice. This product USES fiber as transmission medium, improve the system transmission performance, effectively avoid the bad environment by lightning, surge and electromagnetic interference on the threat of communication equipment.

Key features:

Support the RS - 232 interface, asynchronous transmission, point to point application, rate of 120 KBPS

Support 5 v power input, output voltage - 14 v to + 14 v, power consumption 2 w

Maximum communication rate 120 KBPS

External for + 5 VDC or 220 vac power, without QieDian serial port, a wider adaptability

Multimode optional ST/SC/FC interface, single mode using FC/SC/ST interface

Interface with 1500 w surge protection, 15 kv electrostatic protection

Automatically detects signal rate, zero delay automatic forwarding

Multimode communication reach 2 kilometers, single mode can be up to 120 kilometers
